Answer:
Step-by-step explanation:
We can find the inverse function of this excercise, isolating X and then changing the variables.
And now we change the variables and we get the inverse function:
Additive indentity
n = 1
a variable is always a number itself remember 7+n
5+2 = 7

<h3>
Answer: D) 144 square cm</h3>
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.
---------
Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.
